创建一个以数据库名称为参数的MySQL存储过程，以列出具有特定数据库中详细信息的表。

假设当前我们正在使用一个名为“ query”的数据库，并且其中包含以下表-

mysql> Show tables in query;
+-----------------+
| Tables_in_query |
+-----------------+
| student_detail  |
| student_info    |
+-----------------+
2 rows in set (0.00 sec)

现在，下面是一个存储过程，它将接受数据库名称作为其参数，并为我们提供具有详细信息的表列表-

mysql> DELIMITER//
mysql> CREATE procedure tb_list(db_name varchar(40))
   -> BEGIN
   -> SET @z := CONCAT('Select * from information_schema.tables WHERE table_schema = ','\'',db_name,'\'');
   -> Prepare stmt from @z;
   -> EXECUTE stmt;
   -> END //

现在通过提供数据库名称作为其参数来调用此存储过程-

mysql> DELIMITER;
mysql> CALL tb_list('query')\G
